I infer from the "cc" in

	cc: error: unrecognized command line option -Wshorten-64-to-32

that this is UN*X (or Windows with MinGW or Cygwin or something such as that).

If it's UN*X, presumably you can try autotools; with autotools, does the compiler detect that the compiler doesn't support -Wshorten-64-to-32?

If not, the test needs more work in autotools, and those changes might also apply to CMake; if so, this is an issue with the CMake tests for "does this flag work"?
